Program Your Additional KEY

Well, yesterday I spent $95 to make an addition key at dealer. They charged $46.66 for part and $48.95 for labor. This is kind of expensive.
I hope I know how to program the key so I can save $49 but too late now. I just found how to program addition key. You need program the key only your key has chip in it. There are maybe some ways other than this to program the key. Maybe you can save some $$.

To Program An Additional Key:

1) Place an already programmed Master key in the ignition, but DO NOT turn on.
2) Press the GAS pedal five (5) times.
3) Press the BRAKE pedal six (6) times.
4) Remove the key from the ignition.
5) Insert the new key, but DO NOT turn it on.
6) Press the GAS pedal one (1) time only and wait about a minute for the security light to quit flashing.
7) Remove the key and Press the BRAKE pedal one (1) time only.
8) Wait at least ten (10) seconds, then re-insert the new key and start the car.
